That blinking cursor is the way in which the BIOS is telling you that Windows is missing - its most critical, core files have been corrupted beyond repair. The only thing you can do is to reinstall using the recovery cd or your own Windows install disk.If you can't complete the reinstall or it fails immediately after it then it;s hardware - the motherboard has failed. Time for a new one.

No blinking cursor either?

{ If there is a blinking cursor, you would then use the Restoration Disk, IF you have it.
When asked choose Repair. (Non-Destructive Installation)
If you do not have it go to HP Support Worldwide, your country, and obtain the disk. (HP bought out Compaq. On the HP Support page for your country, go to the Top Right, click on the - Connect with HP - icon.

When you hover your mouse cursor over it, Connect with HP will briefly show)
The disk is free. The shipping and handling is not.
USA example: $17 for a 5 to 7 day ship, $24 for a 2 to 3 day ship. Call 1-800-474-6836. 24hrs a day, 7 days a week.

Have your Serial Number handy, to give to the nice representative on the phone. Bottom of the laptop in white Service Tag. S/N = Serial Number }

However no blinking cursor was stated. This means to me that it is a graphics problem.

The problem can be;
1) Graphics chipset
2) Video Cable. (Compaq/HP = Display Cable)

3) Screen Inverter. (IF used. Model Name and Model Number was not stated. This is the Product Number. P/N in white Service Tag, on bottom of laptop.

GENERALLY, if a CCFL is used for a Backlight, a screen Inverter is used. (Cold Cathode Fluorescent Lamp)

IF LED backlighting is used, GENERALLY NO screen Inverter is used. (Light Emitting Diode)
Does depend on what model we are talking about here.
There are some models that have used a screen Inverter, along with LED Backlighting.

4) LCD screen

A) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA connector, on the laptop.
Usually on one of the sides, or back.
Here is a general example of a VGA connector (port), and a VGA Cable,

http://en.wikipedia.org/wiki/VGA_Connector

Scroll down a little for VGA Cable example.

You can use a CRT type of monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable. (You can also use a VGA to DVI adapter, if the laptop has a DVI port on it,

http://en.wikipedia.org/wiki/Digital_Visual_Interface

You can click on any photo to enlarge. Sometimes you can enlarge twice )

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.
IF not;

You have at least 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down, and at the SAME time tap once on the F4 key. The F4 key is the Display Toggle-Over key.

Still no display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F4 key.

NO display on external VGA monitor, means a problem with the graphics chipset.
Most of the time it is the MOUNTING of the graphics chipset TO motherboard.

The solder connections is the problem. Graphics chipset is reflowed to the motherboard, using an SMD/BGA Rework Station. Specialized shops have them.

Otherwise it means replacing the motherboard.

Good graphics on external VGA monitor means the problem is;
1) Video Cable
2) Screen Inverter (IF USED)
3) LCD screen

A Video Cable cost ranges from $9 to $22, with $9 being the norm.
It also just may have a loose connection. Loose at the motherboard side, or LCD screen side. May be screen Inverter cable connection, from Video Cable; is also loose.

So, you are looking at perhaps a loose connection of Video Cable.
Or a damaged Video Cable. (Replace then)

Problem may be the screen Inverter. (IF used)
They range from $9 to $22 also. (Again, $9 being the norm, or less)

LCD screen ranges from $60 to $245.
Just depends on what Compaq laptop it is.

Point?
Better to diagnose.
May find loose Video Cable connection, or bad Video Cable.
May find bad screen Inverter, if Video Cable is not the problem.

Some people jump the diagnostic flowchart, wind up spending $60 to $245 for an LCD screen, ONLY to find the problem was a $9 Video Cable, or FREE if the connection was loose.

Wish I could guide you from here. I step by step guide people, and this means replacing a motherboard in a laptop, if needed.
I have over 10,000 solutions, and many of them are for laptop repair. According to feedback from the asker's of the problems, I seem to have a very high ratio of accomplishment at this, because they repaired their problem/s.
(Brag, brag, lol!)

However it would seem a recent site development change, has rendered replies back from the problem asker, USELESS.
Haven't had a reply in two weeks, or more.
(Neither have the Top Experts)

Th problem is lcd


No display on laptop's internal monitor, and there is no blinking cursor?
Start with seeing if it is a display problem.

Connect a VGA monitor to the laptop. If the display does not show on the external VGA monitor, the problem is the graphics chipset.

You did not state the model number of the Fujitsu laptop, therefore all I can give is generic basic information.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the laptop.
This is an example of a VGA Cable, and a VGA connector,

http://en.wikipedia.org/wiki/VGA_connector

The VGA connector (Port) on your laptop is either on the side, or back of the laptop. May be marked on laptop as RGB.

You can use a CRT type of VGA monitor, (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default the display should show on the external VGA monitor.
If not there are at least 3 display options;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press the Fn key down, and at the same time tap once on the Display Toggle-Over key.

The Display Toggle-Over key is one of the F keys at the top of your keyboard. F1 through F12.
It will have a monitor symbol on it.
(For example most HP laptops use the F4 key )

No display on external VGA monitor? Hold the Fn key down again, and tap once more on the Display Toggle-Over key.

If no display shows on the external VGA monitor you have a bad graphics chipset. Motherboard replacement.

If a display does show on the external VGA monitor, you have a problem with the Video Cable, and/or in the Display Assembly.

Post back with the results, after using an external VGA monitor, in a Comment.

Blank screen


Did it boot all the way? Do you hear the fan running, disk drive spinning? If it sounds like it booted but the display is black, try this:
When you press the power button do you hear fansrunning, hard drive spinning, lights on the computer, hear any beeps or lightsconstantly blinking, hear the DvD/CD drive click and the light on the drawer ofthe DvD/CD turn on for a second or two? If so the laptop is trying toboot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

No display after reboot windows


If it seems like your system is running whereas you hear fans running, hear the hard drive running, see lights, heard the hard drive click during bootup, but there is nothing on the lcd screen then try the following:
1) Try hooking a external monitor to your laptop. It can be any type of monitor even one of the old style fat crt monitors as long as it has a vga cable to connect to the laptop. There is a sequence of keys you might have to hit to get the display to show on the external. Most times you hit the FN (Function key) and hold it while you hit the corresponding F1 thru F12 key that is for display. Usually the correct key will say CRT/LCD or it might have a display icon on it. If the image displays on the external monitor that means the video card is good.
2). Remove the external monitor and reboot the computer again. Now when it is done booting take a flashlight an shine it on the lcd screen. You are looking to see if you can faintly see the icons on the screen. If they are there but barely visible then the LCD Inverter is bad. The LCD Inverter is located at the bottom of the lcd screen just above the keyboard and the Strip around the lcd screen covers it. You'll have to take the lcd apart to get to it.
3) If you don't see anything when you shine a flashlight on the desktop, then the lcd screen has to be replaced. However, sometimes the cable on the back of the lcd screen has come aloose or just needs reseating, so unplug the cable and put it back then see if it shows an image.


Read Below if it is not booting at all when you press the power button.
Laptops don't boot for the following reasons: 1) Bad Power Cord. 2) Bad DC Power Jack where the power cord plugs into the laptop. 3) Static Charge Buildup. 4) Bad Motherboard.

The above 4 reasons are when you press the power button and absolutely nothing happens. You hear no fans running, no disk drive running, no one time clicking sound on the CD Drive and No light for a second or two when the CD drives click. In the case of a motherboard issue sometimes you will hear beep sounds or see blinking lights. Those beep sounds and blinking lights tells the technician what is going on with your motherboard and why it will not boot. If you see the blinking lights or hear beeps count them.

So you have a power light which means your power cord and dc power jack is good. So lets see if you have a static charge buildup.

Remove the Power Cord and the Battery from the laptop, then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back into the laptop, but leave the battery out. Press the power button to see if it boots. If it does you had a Static Charge Buildup and it's ok to put your battery back in. If it does not you more than likely have an issue with your motherboard.

This issue is most often caused by a faulty LCD backlight. You can confirm this by connecting an external monitor to the laptop and rebooting it. If you get video on the external monitor, then you will want to have the LCD repaired

Gateway laptop seems to boot, but no screen and cannot do anything. Seems to boot up, but nothing at all is on the screen (not even the cursor). Power and wireless lights are on, can hear CD drive scan and...


Can you hear sound playing as if it were loading the Windows desktop? If so, there are are a few things to check for:

  1. Look VERY closely at the screen once the laptop is on. Can you make out very faint images? They will be hard to see and it's best to be in a well lit area at the time. If you do see images, then the backlight on your LCD screen has gone out. You will need a new LCD most likely.
  2. If you don't see any image at all, try plugging an external monitor into the laptop and booting up the laptop. If you see an image on the external monitor but not the LCD, then you may have a bad inverter/cable/LCD.
If you cannot get an image on the external monitor either, then your video card may be bad. Considering that a lot of laptop video cards are built-in to the motherboard, you may be looking at having to replace the motherboard of the laptop (about 2/3rds the cost of the laptop).

There may be other problems at hand, but those are the most common I've found in this type of situation.

No signals. screen is blank. power green light is blinking.


Its not a malfunction. blinking light is indicator shows that no appropriate input signal detected. If you are using laptop refer your user manual to toggle to external display device. For example in most of the Toshiba Laptops requires to use Fn+F5 in order to use external display device like you have. If issue still persist you may post again by including the details of your laptop/desktop model.

Good Luck, Happy New Year
